Rolls mic preamp
Used one for 20 years, worked great, clean sound, still working. Bought 2nd one as need 2 Rolls preamps with phantom power for testing with 2 calibrated Microphones. Owned other Rolls products, never had a problem. Great company.

Accurate easy to use
Used in small auditorium to test air quality. Very accurate, easy to use. Batteries lasted over 30 hours. Was dropped to the floor several times with no damage. After a few meetings testing air co2 easily indicated what problems existed and with this data could determine steps needed to remedy the problem. Of course a knowledge of air properties and basic HVAC Is

Good product
Works every bit as good as the Dremel discs at 4 for $5. Used Dremel tool for 20 years, as good as any others but much cheaper! Thanks for a fine product at a great price.
